All eastbound lanes of the 210 freeway between Rosemead Blvd and Santa Anita Avenue will be closed overnight Wednesday, Aug. 1, from 11 p.m. until 5 a.m. Thursday, Aug. 2. Before and after that one or more lanes will be closed at various times as construction crews pour concrete for the bridge deck. The work is part of the effort to complete installation of the forms and reinforcing steel for the deck of the bridge over the freeway that will carry the Gold Line Foothill Extension trains beginning in 2016.
